I see John Cleese has unleashed a shítstorm by the simple expedient of stating a fact

So if it was full of yanks and aussies it would be ok? But not black people who have lived here for four generations? That makes it a non English city?

In terms of integration, yes, it would be preferable. Failing that, it would be better if it were white, Christian Europeans. The reason being that such groups for cultural and religious reasons tend to integrate more successfully into a white, Christian, European culture. In fact, such groups integrate so successfully that they are largely indistinguishable from the indigenous population within a generation.

Let's not pretend race is not a factor in emphasising difference. It is - indeed is encouraged as such by much of the woke left. So you can't really blame white British people if they feel alienated in the city in which their forebears have lived for hundreds of years because the ethnic and racial make-up of that city have changed so precipitously.
